Earlier this year, Transport Canada released a volley of new regulations around legal drone use in Canada. Now they've updated those rules in Interim Order No. 8 - Respecting the Use of Model Aircraft.

Of course, if you're flying commercially you'll still need to get an SFOC. You'll also probably need one if you're flying recreationally in an urban area.

Here are the most interesting parts of the new order:

1. Distances from aerodomes are reduced from 9km to 5.5 km (three nautical miles), or 1.8 km (one nautical mile) in the case of "an aerodome or heliport that is used exclusively by helicopters."

2. For models under 1kg there is a change to operating distance requirements.

These rules apply to drones that weigh more than 250 grams, up to 35 kg.

(3) No person shall operate a model aircraft having a totalweight of more 250 g (0.55 pounds) but not more than 1 kg(2.2 pounds) at a lateral distance of less 100 feet (30 m)from vehicles, vessels or the public, including spectators,bystanders or any person not associated with the operationof the aircraft.(4) No person shall operate a model aircraft having a totalweight of more 1 kg (2.2 pounds) but not more than 35 kg(77.2 pounds) at a lateral distance of less 250 feet (75 m)from vehicles, vessels or the public, including spectators,bystanders or any person not associated with the operationof the aircraft.

If you're looking for places to fly, the National Research Council of Canada has a handy UAV Site Selection Tool. Here's a screenshot of restricted airspace taken from the UAV Site Selection Tool of the Greater Vancouver Area.
